WINDOW-SCREEN.

SPECIFICATION forming part of Lettersl Patent No, 288,943, dated November 20, 1883.

Application tiled September 3, 1883. (No model.)

To all whom- 'it mrtg/concern.-

Be it known that I, EDWIN HUNTER, a citizen of the United States, and a resident of Allentown, Lehigh county, Pennsylvania, have invented an Improvement in IVindow-Soreens,

oi' which the following is a specication. y My invention consists of a window-screen composed of two frames constructed and adapted to eac-h other, substantially as dero scribed hereinafter, so th at the screen can loe easily expanded and contracted.

In the accompanying drawings, Figure 1 is a perspective view of my improved windowscreen with part of the netting removed; Fig.

i5 2, a vertical section (drawn to an enlarged scale) on the line l 2, and Fig. 3 a sectional plan on the line 3 4.

The screen consists of two quadrangular frames, A A', fitted with wire gauze or netting B. The frames are precisely alike in the present instance, although one may be longer than the other without departing from the main feature of my invention, each frame being composed of the two horizontal bars a a. .and two vertiealend bars, b b', the latter be ing twice as thick as the former. A portion of the upper end of the vertical barb of each frame under-laps the upper horizontal bar, a., of the adjoining frame, and a portion of the lower end of the vertical bar b of one frame overlaps the upper edge of the lower bar, a', of the adjoining frame; or, in other words, part of eaehhar b iits snugly, but so as to slide freely,in the adjoining frame,between the upper and lower hars thereof, as will be best underst-ood by reference to Fig. 2. There is a longitudinal groove in the under edge of the upper bar and a similar groove iii the upper edge of the lower bar of each frame, and each vertical bar b is furnished with two rollers, d, 4o the rollers of one frame fitting freely into the grooves of the other frame. Thus it will he seen, on reference to Fig. 2, that the portion of the bar b of the frame A which projects into the frame A has two rollers, one adapted 4 5 to the groove in the upper bar of the frame A and the other fitting in the groove in the lower bar of the same frame. In like manner the rollers of the frame At in the grooves of the horizontal bars of the frame A. These 5o rollers not only serve to maintain the two frames of the screen in their proper position laterally, or, in other words, to keep the frames together, but also permit the screen to be easily extended or contracted longitudinally.

I claim as my invention- The within-described extension-screen, the same consisting of two frames, A A, a portion of one projecting laterally into the other, and the projecting portion of one frame carrying 6o rollers adapted to grooves in the upper and lower longitudinal bars of the other frame, all substantially as set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing Witnesses.
